' Measuring Valves; and I do hereby declare the following to be a full,

clear, and'e'xact description of the invention, such as will enableothers skilled in the art to which it ap .ertalns to make and use thesame.

y-mvention relates to new and useful unprovements in dispehsin ormeasuring valves and more particular y to that class adapted to be usedfor dispensing liquid soaps or similar articles and my object is toprovide means for discharging'a pro-determined j ua-ntity of the liquidat each '.oper- 'ation o the valve stem.

A further object is to provide pocketsor recesses on diametricallyopposite sides of the valve stemand so arrange said ockets whereby thepockets will be broug t into position to be filled or emptied byturning.

the stem a quadrant of a circle.

A further object is to provide suitable filling and discharging openingsfor the casing of the valve and a further object is to provide means forpreventing bubbles forming in the discharge opening. Other objects andadvantages will be heremafter referred to and more particularly pointedout in the claims.

In the accompanying drawings forming part of this application, Figure 1is a perspectlve view of the valve complete. Fig. 2 1s a transversesectional view thereof as seen on line 2*2, Fig. 1. Fig. 3 is a verticalcentral sectional View through the valve casll'lg Fig. 4 is a sectionalview through the casing as seen on line 44, Fig. 3. Fig. 5 is aperspectlve view of the stem of the valve removed, and, Fig. 6 is a planview of the washer used in connection with said stem.

Referring to the drawings in which simi lar reference numerals designatecorresponding parts throughout the several vieWS, 1 indicates thecaslng' of m improved valve, through the center of which extends a boreor socket 2, for the-reception of the valve stem 3, said bore and stembeing slightly tapered from end to end as is the usual practlce. v

.tudinal center is an inlet and outlet port l and 5, respectively, theinner ends Gland of said ports be ng preferably oblong or flaredupwardly or downwardly fora purpose to e hereinafter set forth. Theortion of the casin through which the inlet port 4 is extended, isprovided withthreads 8,] whereby the valve may be readily attached toany suitable form of pipe or other object.

The stem iiis'pi'oviclcd on diametricallv opposite sides with pockets orrecesses 9 and 10, said pockets being separated by a partition 11, whichpartition is substantially fan shaped at its'edges to form cut ofl's l2vand 13, which cut oii's are adapted to cooperate, respectively, withthe inlet and out let portions at and 5, the width of said cut offsbeing sli htly greater than the width of the inner ends 6 and 7 of theinlet and outlet port-s, respectively.

The length of the pockets 9 and 10 are substantially equal in length tothe inner ends 6 .and 7 of the inlet and outlet ports.

f'wherc'by when the pocket-sure brought into registration with saidports, the discharge and intake of the liquid passing through the valvewill be quickly accomplished.

The extent of the pockets 9 and It) is such that when the cut off valveis resting at one side of the inlet 4. a supply of the liquid will bedeposited in the pocket '10. the cut oil '13 will be positioned at theopposite side of the outlet poi-t5- and in "position to dis charge thecontents of the pocket 9 as shown by .full lines in Fig. 2 and byrotating the stem the quadrant of a circle,.the cut oil s l2 and 13 willbe moved to opposite sides of their respective ports as shown by dottedlines in Fig. 2,thus bringing the pocket 9 to be filled through theinlet port. and pocket 10 in position to discharge its contentsthroughthe outlet port- 5, the movement of the stem being limited to theproper extent by providing a channel 1a in'thc upper end of the casin 1,in which travels a pin 15 carried by t e stem 3, the longltudmal ex tentof said. channel being such as to permit a quarter rotation ofthe stem.In this nannor, a predetermined quantity of the l1qu1d will bedischarged with eachoperation of the valve stem and to guard against agreater amount of the liquid being discharged as the stem is beingrotated; the

cut oils will completely close their respcctire ports while said cutoffs are being:

moved from side to side of their respective ports.

It has been found by experience that the dispensing valves for liquidsoap w ll become inoperative by bubbles forming across the outlet portand it has beenthe practice heretofore to provide air vents to overcomethis objectionable feature, but said air vents were found to bedefective. To this end, therefore, I provide a plate l6,'preferably ofthin metal and positioned in the outer .tioning the same substantiallyat the axial center of tli'e outlet port and projecting it beyond orbelow the lower end of the outlet port will sever or destroy the bubblesas they are formed in the liquid running downwardly.

The upper end of the stem 3 terminates in a lever or handle 17, wherebythe stem may be readily rotated when desired, while the lower endterminatesin a shank 18, a portion of which is providedwith threads 19to receive a nut 20, while that portion of the shank adjacent the stemforms a bearing sur:

face for a washer 21 and to cause the washer to rotate with the stem andlikewise the nut to rotate with the washer and thus prevent- ,ingloosening of the nut by turning the stem, the tank and washer areprovided with cooperating fiattened portions as shown in Figs. 5 and 6.

In operation,'the valve is attached to any suitable form of shank orrece tacle for holding the liquid, more especia ly, li uid soap, throughthe medium of pipes tnot shown) or direct to the receptacle, said valvesbeing preferably positioned over a wash basin and where a plurality ofbasins are arranged in juxtaposition to each other, a valvemay bepositioned over each of the basins and connected to one reservoir orreceptacle through various ipe sections, thus obviating the necessity 0providing a tank for each valve.

When it is desired to obtain the soap, supposing the stem to bepositioned as shown by full lines in Fig. .2, t e lever 7 'is swung tothe left until the pin 15 has traveled the full length of the channel14, thus rotating the stem a quadrant of a circle and positioning thesame as shown by dotted lines in Fig. 2.

This operation disposes the filled pocket 10 in position to dischargeits contents throu h tlie o utlet port 5 and brin s the pocket 9 inposit on tobe filled throng the inlet port 4-, and if a suflicientquantity of the soap is not obtained with one operation of the lever,said lever is again swung in the opposite d rection and thesupplycontained in the pocket 9 discharged.

It will thus be seen that I have provided a very cheap and economicalform of dispensing valve and one that will discharge a predeterminedquantity or the liquid being dispensed and thus obviatin the possibilityof accidentally wasting the liquid.

It will further be seen that a number of the valves may be employed andconnected to one source of supply and further that the supply of liquidcan be obtained with but a slight movement of the stem of the valve. Itwill further be seen that by forming the inner ends of the inlet andoutlet ports oblong, the intake and discharge of the liquid Wlll befacilitated and that by providing the late in the outlet port, cloggingof said port y bubbles forming in the liquid will be obviated.

It will be understood that when the device 1 is'placed in its operativeposition, the plate 16 will point downwardl What I claim is:

1, In a device of the character described, the combination with a valvehaving its plug member provided with a li iiid receiving pocket and acasing for sai plug having inlet and outlet ports, of means arrangedsubstantially in the line of the axial center of the outlet port forutilizing the action of capillary attraction upon the dischargingliquid.

2. A device of the character described, consisting of a valve having itscasin prov ded with inlet and outlet ports, an provided with a partitionarran ed in substantially the axial center of said outlet port,

said partition projecting beyond the discharge end of said outlet.

- 3. A device of the character described, consisting of a valve providedwith inlet and outlet ports and a partition arranged substantially inthe axial center of the outlet port and projecting beyond the dischargeend of said outlet port, the projecting end of said plate being taperedto a point.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
